# Airport XML Properties<no value>
This page lists most of the different elements and attributes required to generate properly formed XML for an **airport**. Most of the XML shown, is created for you when you use [The Scenery Editor](../../../devmode/editors/scenery-editor/the-scenery-editor/) tool - included as part of the [Developer Mode](../../../devmode/developer-mode/) toolset within Microsoft Flight Simulator 2024. As such, we recommend that you use that tool instead of trying to create your own XML from scratch, and use this page as a reference if you need to edit the files the Scenery Editor creates.

{{< callout context="caution" title="IMPORTANT!" icon="outline/alert-triangle" >}}

When doing work on an already existing airport in the simulator, by default the behavior is to add the new set of data to the existing airport and not to replace the corresponding data. If the objective is to replace the previous set of data, then it is necessary to use a `<DeleteAirport>` element to describe what is to be replaced.

{{< /callout >}}

 

Note that this page covers the XML required for the *airport* and some of it's facilities, but other things like runways and approach routes are *not* included here to keep the information in more manageable blocks. The links below cover the things that are not included on this page, and all of them would be used within the `<Airport>` container element:

-   [Runway XML Properties](runway-xml-properties/)
-   [Approach XML Properties](approach-xml-properties/)
-   [Taxiway XML Properties](taxiway-xml-properties/)

 

Finally, the XML document for an airport **must have the following format**:

``` xml
<?xml version="1.0" encoding="utf-8"?>
    <FSData version="9.0">
        <Airport>
            
        </Airport>
    </FSData>
```

 

 

### &lt;FSData&gt;

The `<FSData>` element is the top level container which contains the `<Airport>` sub-element (and can also contain various other [Scenery Editor Object XML](../scenery-objects/scenery-xml-properties/) elements). It has the following possible attributes:

 

<table><thead><tr class="header"><th>Attribute</th><th>Description</th><th>Type</th><th>Required</th></tr></thead><tbody><tr class="odd"><td><p><code>version</code></p></td><td><p>The current version of the XML file.</p><p><strong>IMPORTANT!</strong> The <code>FSData</code> container element <strong>can only be version "9.0"</strong> and anything else will fail to parse.</p></td><td>String</td><td>Yes</td></tr><tr class="even"><td><p><code>timestamp</code></p></td><td>The file timestamp.</td><td>String</td><td>No</td></tr><tr class="odd"><td><p><code>patch</code></p></td><td>The patch number for the file.</td><td>String</td><td>No</td></tr><tr class="even"><td><p><code>source</code></p></td><td>The original source of the file.</td><td>String</td><td>No</td></tr></tbody></table>

 

 

### &lt;Airport&gt;

The `<Airport>` element is used to indicate the placement of airport facility information. Airports are placed according to their airport reference point and may contain a large amount of data, with the element containing one or more of the following sub-elements:

`<AirportArchetype><ApronControl><Tower><Services><Com /><Runway><RunwayAlias><Ils><Aprons><PaintedElements><DetailPolys><ApronEdgeLights><LightPreset><LightSupport /><AirportGroup /><Group><TaxiwaySign /><TextMarking><Waypoint><Departure><Arrival><Approach><Ndb><Helipad><Start /><Jetway><VDGS><ProjectedMesh><VectorPlacement><BlastFence><BoundaryFence><DeleteAirport><HoldingPattern><WasmModule />`

The following elements are also used in the creation of airports, and - if used - they **must** be defined in the given order:

1.  `<TaxiwayPoint />`
2.  `<TaxiwayParking />`
3.  `<TaxiwayParking />`
4.  `<TaxiwayServiceStand />`
5.  `<TaxiName />`
6.  `<TaxiwayPath>`

 

The airport element has the following attributes:

#### &lt;ParamOverride /&gt;

This is a self-closing sub-element of `<AirportArchetype>` and is used to define a single parameter to override and the value to override it with. You may include multiple of these elements to override several of the available properties for any airport, for example:

``` xml
<AirportArchetype>
    <ParamOverride name="RunwayTireGumOpacity" value="0.0"/>
    <ParamOverride name="RunwayCrackOpacity" value="0.0"/>
    <ParamOverride name="RunwayPatchOpacity" value="0.0"/>

### &lt;ApronControl&gt;

This a sub-element of the `<Airport>` element and is used to add one or more **Airline Codes** for airport services. Each airline code registers a new **Apron Control Unit** for use at the airport and enables the airport and other objects to request and use the advanced services that can interact with other airport objects and aircraft. If you do not supply an Apron Control airline code, then this will mean that the airport has to use "fallback" services, which aren't as comprehensive. Note that you can add multiple `<ApronControl>` elements and each one will create a new apron control unit with the designated airline code. Normally, this is the procedure for airports with multiple gates and aircraft parking spots, as you would want to have one control unit per gate (or cluster of gates).

 

For more information on the advanced setup of Apron Services, please see here:

-   [Apron Services](apron-services/apron-services-overview/)

Latitude of the text marking, in degrees between -90.0° and 90.0°.

Float

No

`lon`

Longitude of the text marking, in degrees between -180.0° and 180.0°.

Float

`heading`

Facing angle for the text marking. Value between 0° and 360°.

Float

`scale`

The scale multiplier for the text marking. A value of 1 is the default scale.

Float

`letterSpacing`

The horizontal spacing offset between the letters of the text. Setting this to 0 uses the default spacing, while larger numbers will increase the spacing and lower numbers will decrease it.

Float

`lineSpacing`

The vertical spacing offset between the lines of the text. Setting this to 0 uses the default spacing, while larger numbers will increase the spacing and lower numbers will decrease it.

Float

`paddingX`

Sets the visual padding around the text on the horizontal axis. Setting this to 0 uses the default padding, while larger numbers will increase the padding and lower numbers will decrease it. The effect of this value is only visible when you have set either `drawBackground` or `drawOutline` (or both) to "true".

Float

`paddingY`

Sets the visual padding around the text on the vertical axis. Setting this to 0 uses the default padding, while larger numbers will increase the padding and lower numbers will decrease it. The effect of this value is only visible when you have set either `drawBackground` or `drawOutline` (or both) to "true".

### &lt;Start /&gt;

This a sub-element of the `<Airport>` element and is used to designate one or more helipads in the airport to be used as possible start locations for a flight. Note there should be at least one `<Start>` element defined for each `<Helipad>` element.

{{< callout context="caution" title="IMPORTANT!" icon="outline/alert-triangle" >}}

In previous versions of the simulation this was parsed for both Runways **and** Helipads. However that is no longer the case and this element **only applies to helipads**, while runways should use the dedicated `<RunwayStart />` element instead. Airports created in previous versions will have this element automatically updated to a runway start element on import, if the `type` parameter flags it as such.

{{< /callout >}}

 

This is a self-closing element and has the following attributes:

 

<table><thead><tr class="header"><th>Attribute</th><th>Description</th><th>Type</th><th>Required</th></tr></thead><tbody><tr class="odd"><td><code>number</code></td><td>Number of the runway to start on.

### &lt;Jetway&gt;

Jetway elements are part of an `<Airport>` element, and must contain a single `<SceneryObject>` element. One jetway can service at most one parking spot. A jetway will be animated and will usually come in to the main exit on the left side of the aircraft. AI controlled aircraft will also trigger the animation of the jetway. To replace jetways at an airport, use the `<DeleteAirport>` element with the `<deleteAllJetways>` field set to "TRUE", then enter the new jetway elements. Note that all parking spots do not require jetways.

 

The available attributes for jetways are as follows:

### &lt;VDGS&gt;

A **VDGS** object is part of an `<Airport>` element, and is used to add a [Visual Docking Guidance System](https://en.wikipedia.org/wiki/Stand_guidance_system "Visual Docking Guidance System - Wikipedia") to a stand at an airport. This element requires the `<SceneryObject>` sub-element to define the scenery object to use as the VDGS, and also requires the following attributes:

### &lt;BlastFence&gt;

### &lt;BoundaryFence&gt;

These are both sub-elements of the `<Airport>` element and are used to define a blast and boundary fences. Both elements require at *least* two `<Vertex />` sub-elements to define the points between which instances of the given model will be placed, as well as a `<Model />` sub-element to define the model that is used.

 

They also have the following attributes:

### &lt;DeleteAirport&gt;

This a sub-element of the `<Airport>` element and is used to remove certain features from the area the airport occupies. Since most of the airports that are going to be edited are preexisting airports within the simulator, it is important to understand the behavior behind the `<DeleteAirport>` structure: when loading two packages that cover the same airport, the simulator will load *both* versions of the airport from each package, adding the data from each package together, rather than overriding one package with another. In the case that this is not what you want, you need to use this element to remove features from any previously loaded airport (including those that are defined as part of the base sim).

 

This element can have the following attributes:
